In their enthusiasm for chapters, however, early Christian editors and writers introduced a problem, one that cut to the heart of their own sacred texts and presaged the challenge that chapters present to writers even today. How do you segment continuous, narrative texts rather than informational ones? How, for instance, do you divide Scripture—like the Gospels—into bits, given that they were written as one continuous text, undivided and unlabelled? At first, the problem must have seemed merely technical. Eusebius solved it by devising an elaborate system of small sections cross-indexed among the different Gospels, one that remained popular well into the Middle Ages, but it was cumbersome: there were over three hundred such sections in Matthew and Luke each. The Bibles of late antiquity and early medieval culture contained a bewildering variety of chaptering systems to complement or replace Eusebius’s sections, and each system had its own sense of what counts as a significant unit of action or a significant moment deserving of its own heading. To divide, it turns out, is already to interpret.
